Benefits of technology

The patent is about a device and method that can measure multiple material properties, such as thermal conductivity, electrical conductivity, and surface temperatures, in a single sample without moving it. The device includes a structure and sensors that can measure these properties simultaneously without using separate instruments. The method can use the measurement of the temperature of a reference sample to calibrate the thermocouple probe temperature. This technology allows for more efficient and accurate analysis of samples.

Problems solved by technology

Electrochemical energy storage devices are based on changes in chemical potential during a reduction / oxidation reaction, with the rate of charge and discharge limited by ionic conductivity.
Energy dissipation is mainly due to Joule heating in the device, where charge flow between anode and cathode is impeded by the resistance of the separating medium.
Currently different instruments are used to measure the electrochemical performance of fabricated cells and packs with limited ability to obtain temperature dependent performance and surface temperature during operation.

Abstract

A device for measuring a plurality of material properties includes a structure and sensors in the structure configured to sense at least thermal conductivity, electrical conductivity, and Seebeck coefficient for a single sample consecutively while maintaining a vacuum or inert gas environment. Embodiments can also measure ionic conductivity and / or surface temperatures. Embodiments can measure any suitable plurality of the above properties.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to and the benefit of U.S. Provisional Application No. 62 / 554,432, filed Sep. 5, 2017, the contents of which are herein incorporated by reference in their entirety.BACKGROUND1. Field[0002]The present disclosure relates to instruments for measurement of multiple material properties (e.g., for measurement of Seebeck coefficient).2. Description of Related Art[0003]Obtaining accurate knowledge of electrical and thermal properties of manufactured materials has significantly broad implications in various industries as these properties are fundamental to any material system, which affects quality control aspects needed for the integrity of cyber-physical and energy systems engineering.[0004]Thermal energy harvesters are based on the Seebeck effect. The Seebeck effect is a phenomenon in which a temperature difference between two dissimilar electrical conductors or semiconductors produces a voltage difference betwe...
